Filter values using context
You can use one or more items to quickly focus your
exploration on a particular view of the data. This technique is
known as filtering using context.
For example, you have a crosstab showing products in the rows and revenue for different quarters in the columns. To change the context to Asia, you drag Asia from the source tree to the Context section of the overview area. The crosstab then shows only the values for Asia.
Changing context changes the values that appear. It does not limit or change the items in the rows or columns.
You can filter using multiple values in the context area, however, multiple filters are lost when you convert the exploration to formulas and start to use cell-based methods. Some context filters cannot be converted to formulas, such as multiple filters from the same dimension and filters from dimensions that are already displayed in the exploration.
